Cillian Murphy Finally Answers the Voldemort Question in the Harry Potter Reboot

Cillian Murphy has ended the Voldemort chatter—he won’t play the Dark Lord in HBO’s Harry Potter series. With casting still under wraps, He Who Must Not Be Named remains, fittingly, unnamed.

Cillian Murphy just put a big, clear stamp on the Voldemort rumors. If you were picturing the Oppenheimer and Peaky Blinders star hissing around Hogwarts in HBO's upcoming Harry Potter series, time to recalibrate.

Murphy settles it

Asked point-blank if he is playing the Dark Lord, Murphy did not hedge.

"I am categorically not. Can you make that the headline?"

He also made it clear he has zero interest in feeding the fame machine. The endless chatter, the red carpets, the mythology that builds around actors — he sees it as a trap and says he does not buy into it. In his words elsewhere, he is not out to be a personality, just a regular guy who acts.

He has been here before

This is not the first time he has knocked down the story. On the Happy Sad Confused podcast, Murphy said his kids sometimes flag the speculation for him, but there is nothing official behind it. He also gave Ralph Fiennes his flowers, calling him an absolute acting legend and saying it would be very hard to match what Fiennes did as Voldemort. Whoever takes the part, he wishes them luck.

Fiennes is into the fancast

Funny twist: Fiennes himself likes the idea of Murphy taking over. On Watch What Happens Live last year, he backed the concept without hesitation.

"He is a fantastic actor... I actually think that is a wonderful suggestion. I would be all in favor of Cillian."

So who is Voldemort this time?

Here is where it gets interesting. Behind the scenes, the role is reportedly already cast and the character is set to appear in several episodes. The plan, according to a source close to production, is to keep the actor's identity under wraps until the first season launches in 2027. For now, the public face of the Dark Wizard remains a mystery.

The other rumor with Murphy's name on it

Separate from the Voldemort chatter, one well-known industry scooper claimed on Patreon that Murphy was in the mix to play Professor Quirinus Quirrell in the series. That is rumor territory, but it is out there.

Where things stand

• Cillian Murphy says he is not playing Lord Voldemort. Full stop.
• He previously dismissed the rumor, said there is nothing official, and praised Ralph Fiennes as a tough act to follow.
• Ralph Fiennes is game for a Murphy Voldemort, calling him a fantastic actor and backing the idea.
• Voldemort is reportedly already cast, will appear across several episodes, and the reveal may wait until the 2027 season premiere.
• A separate rumor links Murphy to Professor Quirrell, but that remains unconfirmed.
